Abstract (en)
[origin: EP0807544A2] The ventilation circuit allows switching from a fresh-air mode to a recirculation mode when a sensor detects harmful particles in the external air and in dependence on the external air temperature provided by a second sensor. The sensitivity of the switching device to the output signal from the first sensor is dependent on the temperature sensor output signal, The opening ratio for the fresh air intake can be reduced in stages in response to a decrease in the external temperature.
